The power variations are mainly supplied by the supercapacitor and the lithium ion battery functions as a backup. In this regard, the proposed system saves $ 2205,724 by supplying energy to the tramway and selling the excess energy to the grid for 20 years. Finally, the renewable system will have avoided 8445.4 tCO2 /MWh.
Advances in control systems to supply traction power to a tramway have been significant. However, there are gaps in the investigation that must be filled. In the present energy management system, there is no primary renewable source to supply storage systems like SC or batteries.
An alternative is catenary free trams, driven by on-board energy storage system. Various energy storage solutions and trackside power delivery technologies are explained in , .
The system has been modeled in Matlab considering certain restrictions in each component in order to supply the load on the round trip. Finally, a techno-economic and environmental analysis has been done identifying new patterns with respect to existing tramway systems. The annual energy required by the tramway is 867.62 MWh/year.
Abstract: Catenary-free trams powered by on-board supercapacitor systems require high charging power from tram stations along the line.
The proposed energy control orders that the energy sources are in constant operation depending on the renewable resource in each interval recharging SC and LIB, if there is not enough energy, the system must supply the tramway by buying energy from the electrical grid, and the excess energy is sold to the grid.
